Our universe is an amalgamation of different objects following a wide spectrum of sizes, ranging from the smallest particles to the jumbo astronomical objects. being able to perceive the nature and behavior of all these sizes has been one ultimate goal of mankind since ages. But, as a single medicine cannot cure all the diseases, Similarly, a single scientific theory cannot work well at all the scales. So where we can efficiently describe the motion of a billiard ball or the motion of the planets around the Sun, using the same laws we cannot describe the behavior of smallest entities in the nature. This is where quantum physics comes into picture. But what it really is? What led to the development of this theory and how is it different from classical physics? This is Q and A and here is the answer to the ques What is Quantum Physics?

In the late 1970s, two physicists in Switzerland set out to invent a new type of microscope using quantum physics that would allow them to do something no one had ever done before: see the individual atoms in a sheet of metal.
Scientists are building a wormhole tunnel analogue in quantum circuits
Scientists have proposed to build a functional wormhole tunnel by simulating quantum entangled black holes in a lab. Quanta Magazine reports the linked black holes are theoretically able to teleport quantum information via the tunnel.
Black holes were thought to totally obliterate the objects they consume. However, the experiment will test a new idea in physics that evaporating black holes actually send information about subsumed objects back to the universe via Hawking radiation.
Citing California Institute of Technology physicist Sepehr Nezami, the outlet reports the research team believes a black hole could be forced to disgorge intact information after it is entangled with another black hole on a quantum level.
Stanford University’s Adam Brown is cited as saying quantum circuitry could make a functional analog for entangled black holes. If the theory is correct, this circuitry would be able to instantly transmit and decrypt qubits, also known as quantum teleportation.
Craig Callender – What does Quantum Theory Mean?
Quantum theory may be weird—superposition and entanglement of particles that in our normal world would make no sense—but quantum theory is truly how the microworld works. What does all this weirdness mean? How to go from microworld weirdness to macroworld normalcy? Will we ever make sense out of quantum mechanics?
Quantum computing and quantum supremacy, explained
Quantum computing could change the world. It could transform medicine, break encryption and revolutionize communications and artificial intelligence. Companies like IBM, Microsoft and Google are racing to build reliable quantum computers. China has invested billions. Recently, Google claimed that it had achieved quantum supremacy – the first time a quantum computer has outperformed a traditional one. But what is quantum computing and how do quantum computers work?
Quantum Impact: Bringing the power of quantum to chemistry (Ep. 3)
Chemistry helps make up our world – yet there is still a lot we don’t know. Because our most powerful classical computers are limited in the chemical modeling they can perform, so are the solutions they can unlock. But quantum computing could change that. On this episode of Quantum Impact, Dr. Krysta Svore, general manager of quantum systems and software at Microsoft, heads to Richland, Washington to meet with Dr. Nathan Baker and Dr. Bojana Ginovska at Pacific Northwest National Laboratory (PNNL). Microsoft is partnering with PNNL to bring the power of quantum to our understanding of chemistry. One of PNNL’s areas of interest is catalysis, or the process of converting chemicals from one form to another, and Nathan shares the complexity involved in truly understanding that process. Bojana, a computational chemist, then speaks with Krysta about her work studying nitrogenase, an enzyme present in healthy soil. She’s exploring how we can turn nitrogen into ammonia for agriculture in a way that doesn’t deplete our energy resources. Together with PNNL, Microsoft is working to develop quantum algorithms to help solve challenging problems in chemistry, which will have hugely positive impacts on our world and our planet’s future.
How do quantum computers work?
Quantum computers are said to have the potential to offer computing power far larger than what we have today. Are they really these miracles of quantum computing or are they just over-hyped? You can have brief information in our video on how quantum computing works related to superpositioning and energy states of atomic particles.
Quantum science at Oak Ridge National Laboratory
The laws of quantum mechanics describe the strange behavior of subatomic particles. Harnessing the power of quantum mechanics could create a technological revolution, and Oak Ridge National Laboratory is leading the way. ORNL experts are focusing on four critical areas of quantum research: computing, materials,
How Decoherence Splits The Quantum Multiverse
Why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many physicists believe that the answer lies in a process known as quantum decoherence.
Does conscious observation of a quantum system cause the wavefunction to collapse? The upshot is that more and more physicists think that consciousness – and even measurement – doesn’t directly cause wavefunction collapse. In fact probably there IS no clear Heisenberg cut. The collapse itself may be an illusion, and the alternate histories that the wavefunction represents may continue forever. The question then becomes: why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many physicists believe that the answer lies in a process known as quantum decoherence.
Quantum Impact: Teaching the next generation of quantum (Ep. 2)
The school of quantum computing is now in session. According to LinkedIn, quantum-related job postings have increased 180% and major universities play a key role in developing the next generation of quantum programmers, scientists, engineers and researchers. This episode of Quantum Impact takes place at the University of Washington, one of Microsoft’s partners in the Northwest Quantum Nexus and home of the QuantumX initiative. Our host, Dr. Krysta Svore, general manager of quantum systems and software at Microsoft, sits down with Professor Kai-Mei Fu, an experimental physics researcher and professor focusing on advanced quantum technologies. Kai-Mei and Krysta discuss their paths to discovering the field of quantum and then, Krysta speaks with students around campus about their quantum research. Finally, they offer advice to students who are interested in exploring quantum as a career path.
